More Information
Summary:The utility model discloses a valve locator which comprises a shell body, a feedback mechanism, a signal input mechanism and a pneumatic actuator. The feedback mechanism, the signal input mechanism and the pneumatic actuator are arranged in the shell body. The feedback mechanism comprises a feedback shaft, a cam disc and a lever. The signal input mechanism comprises a potentiometer and a coil shell body. A coil is connected with the potentiometer and a spring piece a which is connected with a balance rod. The pneumatic actuator comprises a guiding valve and a coupler. The spring piece b is connected with a diaphragm piston. The balance rod is connected with the diaphragm piston through a spring. The diaphragm piston is connected with a spring piece c which is connected with the guiding valve. Through moment balance and electric signals input by the potentiometer, the rotating range of the coil is controlled, meanwhile, coil rotating can directly drive the spring piece a to deform, accordingly, the balance rod
